Project description:Deep-sequencing of the engineered production genes in five E coli production chassis strains (BL21(DE3), MG1655, TOP10, W and W3110) producing two case metabolic products, 2,3-butanediol and mevalonic acid
Project description:The C. elegans lifespan in the presence of Bacillus licheniformis caused induction of a large number of genes associated with anti-aging activiy including beta-oxidation Inaddition, these results indicate the B. licheniformis enhances the lifespan of Caenorhabditis elegans through serotonin signaling
Project description:The C. elegans lifespan in the presence of Bacillus licheniformis caused induction of a large number of genes associated with anti-aging activiy including beta-oxidation Inaddition, these results indicate the B. licheniformis enhances the lifespan of Caenorhabditis elegans through serotonin signaling Two-condition experiment, C. elegans with B. lichemiformis 141 or E. coli OP50 (conrol) for 24 h. For preparing the total RNA, C. elegans were exposed to 20 mg of bacterial lawn in NGN agar for 24 h.
Project description:Clostridium ljungdahlii not only utilizes CO, but also H2 as energy source during autotrophic growth. In theory, CO is a more energetically and thermodynamically favourable energy source than H2 in the gas fermentation of C. ljungdahlii. However, how C. ljungdahlii conserves energy for growth and ethanol/acetate formation grown on CO or CO2/H2 is not in great detail. In this study, C. ljungdahlii was fermented on CO and CO2/ H2 at pH 6.0 with 0.1 MPa gas pressure. C. ljungdahlii produced 27 g/L acetate, 9 g/L ethanol, 8 g/L 2,3-butanediol and traces of lactate in the presence of CO as energy source, while it produced 25.8 0.1 g/L acetate, 1.8 0.1 g/L ethanol, 0.7 0.01g/L 2,3-butanediol and trances of lactate in the same fermentation condition using H2 as energy source. Therefore, comparative transcriptomes between cells grown on CO and cells grown on H2/CO2 were performed to investigate gene expression profiles based on three biological replicates.
Project description:Proteomes of Bacillus licheniformis DSM13 cultivated with glucose, rhamnose as well as ulvan or two ulvan hydrolysates (UHA and UHB). Hydrolysates were generated using selected Formosa agariphila KM3901 ulvan-PUL encoded enzymes.
